Mimas (396 kilometers, 246 miles across) shines in reflected ultraviolet light from the Sun in this Cassini image. Ultraviolet images of Saturn's moons often reveal the walls of their myriad craters in greater contrast than do images taken in visible light. This view, which shows the large impact crater Herschel, is no exception.

The image was taken with the narrow angle camera using a filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The image was acquired on February 18, 2005, from a distance of approximately 938,000 kilometers (583,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 99 degrees. The image scale is 6 kilometers (4 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
